purpose: to determine the visual and anatomical outcomes and complications of vitrectomy for non-traumatic non-diabetic vitreous hemorrhage (ndvh) and to report the causes of the condition among patients at labbafinejad medical center, tehran-iran, from 1993 to 2003. method: records of patients who underwent vitrectomy for non-traumatic ndvh with 6 months follow up were reviewed for demographic...

the term “stunned myocardium” refers to abnormalities in the myocardial function following reperfusion and is common in on-pump coronary artery bypass grafting (cabg) and is exceedingly rare in off- pump cabg. a 53-year-old man presented with unstable angina due to the severe stenosis of the left anterior descending coronary artery (lad) and the obtuse marginal. laboratory findings and chest x-...

conclusions our results support the use of pns in some patients with refractory chronic headaches. appropriate surgical planning and technique are important to achieve good clinical outcome and to minimize complications. background subcutaneous peripheral nerve stimulation (pns) has emerged as a useful tool in the treatment of intractable headaches. however, complications such as skin erosion, ...

BACKGROUND Recurrent laryngeal nerve (RLN) palsy is the most serious complication after thyroidectomy. However, little is known about the degree of traction injury that causes loss of signal. The purpose of this study was to evaluate traction injuries in the swine RLN using continuous intraoperative neuromonitoring (IONM) and determine the traction power that results in loss of signal. METHOD...

Computer modelling of the properties and performance of cement-based materials is complicated by the large range of relevant size scales. Processes occurring in the nanometer-sized pores ultimately tiect the performance of these materials at the structural level of meters and larger. One approach to alleviating thk complication is the development of a suite of models, consisting of individual d...

There have been substantial improvements made in the tools and techniques used since the advent of percutaneous coronary intervention. What was primarily developed as a treatment of coronary artery disease is now used to address a variety of structural heart disease problems. The outcomes have been remarkably successful with relatively low complication rates that rival the results of open-heart...

Infective endocarditis is rare in children and is rarer on a normal structural heart in an infant without any surgical intervention. Most cases are related to a pre-existing congenital lesion, the most frequent etiology are Gram-positive cocci and the most feared are fungal agents. This report presents a 7-monthold infant with fungal endocarditis on a normal structural heart. The diagnosis was ...

Autonomic and peripheral neuropathies are well-described complications in diabetes. Diabetes mellitus is also associated to central nervous system damage. This little-known complication is characterized by impairment of brain functions and electrophysiological changes associated with neurochemical and structural abnormalities. The purpose of this study was to investigate brain structural and ul...
